Art style: Moody Digital Realism.
A close-up of a single firm, unbroken straight line carved decisively into fine pale sand, stretching from the left edge of the frame to the right. The groove is clean and deep, casting a thin sharp shadow. Shot from a high overhead angle with even, diffused daylight from above, cool neutral tones. The surrounding sand is smooth and untouched, emphasizing the deliberate mark. The mood is decisive, minimal, and confident. Dominant palette of soft beige, warm sand tan, and cool gray shadow.

Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Moody Digital Realism" idiom, not in any other medium.
